Title: Electrochemical stain prevention apparatus of submerged structure and process for producing submerged structure used in this apparatus
Inventor: TAKAHASHI HIROMICHI
IPC: B63B59/04
Filed: 1998-08-26
Abstract: An electrochemical antifouling device, comprising an underwater structure of which the antifouling surface comprises an electrically conductive film that does not generate chlorine even if a potential lower than 5 V vs. SCE is applied thereto, an opposing electrode out of contact with the underwater structure, and a power source for supplying a direct current between the underwater structure and the opposing electrode. By applying a potential of from 0.1 to 5 V vs. SCE to the underwater structure, it becomes possible to effectively control underwater organisms adherent to the surface of the electrically conductive film without evolving chlorine. By disposing a reference electrode between the underwater structure and the opposing electrode, the potential applied to the electrically conducting film can be precisely controlled. The electrically conductive film is preferably a spraycoated metal nitride.

Title: Method for combining multiple measurements to determine the position of a mobile transceiver
Inventor: TEKIN IBRAHIM
IPC: G01S5/02
Filed: 2000-01-24
Abstract: Information obtained from one or multiple base stations is used to calculate a mobile terminal's location in a cellular system based on combining multiple estimated locations. The estimated locations are averaged using a weighted sum, where the weights reflect the quality of information or data that produced the estimated location. The estimated locations are based on information such as time difference of arrival (TDOA), time of arrival (TOA), and angle of arrival (AOA). The round-trip delay (RTD) provides TOA information, and the pilot strength measurement messages (PSMM) contain the TDOA information, AOA information and the ID of base stations that provide signals to the mobile terminal.

Title: Tee-mate
Inventor: EDMUNDS LYLE
IPC: A63B57/10
Filed: 2000-04-04
Abstract: A device comprised of a plastic clip, retention peg, plastic/metal composite golf ball tee and an elastic/nylon connecting cord to be used together or in combination while playing golf or when driving/hitting golf balls in practice. This device prevents a golf ball tee from being lost when it becomes dislodged from the drive or hit of a golf club. The retention peg is of substantial length designed with a pointed tip to penetrate the surface of the turf/grass enough, so as to prevent it from becoming dislodged.  The peg will have either a hole or a molded eyelet at the top of the shaft so as to secure the elastic/nylon connecting cord, which will also be secured to the golf ball tee in the same way as the peg. This design prevents a dislodged golf ball tee from becoming lost and eliminates the need to retrieve a tee that has been driven and traveled a substantial distance. The elastic/nylon connection cord connects the retention peg and the golf ball tee when it is secured. The cord will be threaded through the holes and then knotted or secured at its ends or by being secured to the molded eyelet's while also being knotted at its ends.  The elastic/nylon cords purpose is to provide the necessary recoil action to have the dislodged golf ball tee retract back and land close to the retention peg, thus preventing the loss of the tee. The golf ball tee will be made of a plastic/metal composite and/or coated with a membrane being of a consistency that it will provide a durable tee. The bottom half of the tees' shaft will be of hard plastic or metal while the top part is plastic and is of a composite so as to be strong enough to sustain the blows of the golf club, yet soft enough so as to not cause nicks to the golf club face after contact. The plastic clip is designed to hold the retention peg and the golf ball tee for storage between rounds so as to prevent the elastic/nylon cord from becoming tangled and knotted. The clip will also be of such design, that it will be able to clip onto the golf bag, golf cart, or a shirt or pants pocket for convenience and easy access. This product Tee-Mate is designed to be used by golf enthusiasts of all ages and at all levels to prevent the loss of their golf ball tees while also providing a long life tee. Consumers as a result of using this device will eliminate their time currently being spent looking for their dislodged golf ball tee. As a result of preventing the loss of their tee and the durability of our designed plastic/metal tee, golfers will also see a monetary savings due to not having to purchase as many tees to replace their lost or broken tees.

Title: Snowboard
Inventor: STUBBLEFIELD DONALD P
IPC: A63C5/052
Filed: 1998-08-26
Abstract: The invention relates to a snowboard (100), which includes upturned nose (108) and tail (112) portions and a central section (110). Two mounting zones (133 and 135), intended to secure the boots (132 and 134), are located on the central section (110). The central section (110) also includes front (118) and rear (120) cambers, which enable the user to more easily control the snowboard (100). Users of snowboards (100) also have a natural tendency to lean in the direction of travel of the snowboard (100), which shifts the position of the rider's center of gravity slightly forward of the board's midpoint. To compensate, the front camber (418) may be made longer, taller and thicker than the rear camber (420). The front and rear cambers may also include mini-cambers (442 and 444) to further improve the user's ability to control the snowboard (400).

Inventor: PEINETTI DONALD L
IPC: A01K15/02
Filed: 1998-12-18
Abstract: An echo-ranging boundary system (5) is provided for controlling the access of animals (20) to predefined areas (30). An electronic transponder collar (25) is affixed to an animal (20) for exclusion from a predefined area (30). An ultrasonic beacon (10), defining a transmission reference point, periodically transmits a directional ultrasonic interrogation signal for determining the location of animals (20) provided with transponder collars (25). The transponder collar (25) emits an ultrasonic reply signal, detected by the station after a period of time defined by the propagation delay of the ultrasonic reply signal. The propagation delay of the reply signal is directly proportional to the distance between the transponder (25) and the interrogation signal reference point. A timing threshold is set at the transmission station corresponding to a desired control distance. Reply signals returned from a device time-out are compared to the timing threshold.  If the elapsed time of the propagated reply signal is less than the user selected threshold a correction pulse is transmitted to the animal transponder collar (25).

IPC: A61K9/00
Filed: 1999-03-02
Abstract: The present invention provides methods and devices for inducing, stimulating, blocking and reducing the immune response of a mammal to an antigen, using an implantable device which exposes the antigen in a controlled fashion to cells of the immune system. The device comprises a porous matrix contained within a perforated, impermeable container. By manipulating the bioavailability of antigen within the device, and the timing of introduction of antigen into the device relative to the time of implantation of the device within the mammal, a robust and long-term response can be induced against an antigen, or an existing or potential immune response can be down regulated or blocked. The methods and devices can be used for therapeutic vaccination, and in non-exposed mammals for prophylactic vaccination. Immunity can be cellular, humoral, or mucosal. Suppression of the immune response is useful for the treatment or prophylaxis of such conditions as allergies, autoimmune disease, and in tolerizing mammals to suppress an immune response to transplant antigens. The device can also be used for harvesting immune cells for later reintroduction into the mammal, and for preparing immune serum and hybridomas.
